What’s the Answer? Haploview and LD plots?

BioStar is a site for asking, answering and discussing bioinformatics questions. We are members of thecommunity and find it very useful. Often questions and answers arise at BioStar that are germane to our readers (end users of genomics resources). Every Thursday we will be highlighting one of those questions and answers here in this thread. You can ask questions in this thread, or you can always join in at BioStar.

The answer given goes into some detail as to what methods one might want to consider:

I would look at the methods used by Gil McVean and others in determining recombination hotspots across the human genome. I would also read papers by DW Bowden on MYH9 as I know that they narrowed the susceptibility region (end-stage renal disease) with LD and recombination hotspots.

It may be that all three methods are more or less equally informative for your region, thereby giving “fuzzy” boundaries. Recall that LD boundaries are not as precise as a single SNP coordinate – although results from Haploview, HelixTree and others often give that impression.
